The authors describe a method for evaluating arterial hypertension control among the unorganized population visiting polyclinics and organized population taken care of at the medical centers. The method was tried in the city of Chelyabinsk as applicable to a randomized population sample of a medical territorial district and to a randomized sample (8%) of the workers from 9 shops of the steel plant. The method lies in the study of the population health status (arterial hypertension prevalence and knowledge, treatment coverage and efficacy) and of the documentation available at the treatment and prophylactic institutions concerning arterial hypertension control (coverage, registration, scope of examinations, and so forth). It is shown that the method is unsophisticated and feasible for examination of the population and documentation requires 5 days. It is suggested that the method should be used in the study of the situation concerning arterial hypertension control as well as in the study of the problems in the control of other non-infectious diseases.
